How did round planets form from the explosion of the Big Bang?

I completely agree. Combining physics with calculus allows the student to really understand how all the concepts are interconnected.I taught a high-school physics class for 2 years without calculus. Some of the students were not enrolled in calculus yet and hence the class had to rely on intuition. The abstract thinkers were able to connect the concepts together but some of the other students struggled. For the few students who were enrolled in calculus, I took some time to show them how the calculus was involved and they began grasping all the concepts much more quickly.The students could all calculuate velocity, acceleration and kinetic energy. They could calculate forces of gravity. But they couldn't quite understand where gravity came from. However, the ones who were taking calculus really understood how all the concepts intertwined through the mathematics.But. . .
Where have I heard something similar to this before. . . ?Oh yes, Dobzhansky!
"Nothing in Biology Makes Sense Except in the Light of Evolution"People can still do biological experiments without understanding evolution. They can still disect an animal, complete breeding experiments and investigate DNA sequences. But to really understand how all the concepts intertwine you need evolution.Edited by misha, : formatting
